Radio GalaxiesRadio galaxies are active galaxies that possess powerful jets extending to distances of up to 3 million light years. X-ray emission from the jets, lobes and hotspots of radio galaxies is produced by the acceleration of relativistic electrons (synchrotron emission) and/or by scattering of their own radio emission or the cosmic microwave background radiation (inverse-Compton emission). X-ray emission is also observed from the cores of radio galaxies. Radio galaxies are found in groups or clusters, which produce thermal X-ray emission. Combining X-ray and radio observations of radio galaxies has led to many advances in our understanding of radio galaxies and how they interact with their environments. |
